Body weight gain exacerbate both diabetes and obstructive sleep apnea(OSA). Recent reseach dmonstrates that type 2 diabetes and OSA are closely related.
In this study, we analyzed the relation between gained weights and blood sugar control in diabetic patients with OSA.
Twenty-nine male diabetic with OSA (52.6 ± 10.0 years, HbA1c 7.3 ± 1.1%, AHI 58.4 ± 21. 2) were analyzed. Gained weight was defined the weight difference from 18 years old to the time diagnosed as OSA. HbA1c was used for the index of blood sugar control. Their eating and exercise habits were analyzed from the nutrition consultation.
Body weights and BMI significantly increased from 18 years old (69.6 ± 2.1 kg, BMI 24.0 ± 0.8 kg/m2) to diagnosed time (93.7 ± 2.6 kg, BMI 32.3 ± 1.0 kg/m2; p＜0.01). There was no significant difference between the gained weight and blood sugar control. Seventeen patients over HbA1c 7.0% (49.3 ± 10.2 years, BMI 24.8 ± 1.1 kg/m2 at 18 years old, 33.2 ± 1.2 kg/m2 at the time diagnosed as OSA) were younger than 12 patients under HbA1c7. 0% (57.3 ± 7.8 years, BMI 22.8 ± 0.9 kg/m2 at 18 years old, 31.0 ± 1.7 kg/m2 at the time diagnosed as OSA; p＜0.05). Nutrition consultation revealed 89% of patients drink alcohol and 89% of patients eat snacks.
This study may suggest that quick increase in weight after 18 years old is related to the diabetes with OSA. We need to understand how increase their weight, may be the background of eating snack and drinking alcohol
